Adrenodoxin, iron-sulphur binding site
(IPR018298)
Adrenodoxin, putidaredoxin and terpredoxin are soluble 2Fe-2S iron-sulphur proteins that act as single electron carriers. They are a subgroup of the ferredoxin family of iron-sulp...

Pyridoxal-phosphate binding site
(IPR021115)
Pyridoxal phosphate is the active form of vitamin B6 (pyridoxine or pyridoxal). Pyridoxal 5'-phosphate (PLP) is a versatile catalyst, acting as a coenzyme in a multitude of reacti...

RNA polymerases, subunit N, zinc binding site
(IPR020789)
In eukaryotes, there are three different forms of DNA-dependent RNA polymerases transcribing different sets of genes. Each class of RNA polymerase is an assemblage of ten to twelv...

Endonuclease III, iron-sulphur binding site
(IPR004035)
Endonuclease III is a DNA repair enzyme which removes a number of damaged pyrimidines from DNA via its glycosylase activity and also cleaves the phosphodiester backbone at apurini...

Sigma-54 interaction domain, ATP-binding site 2
(IPR025943)
Some bacterial regulatory proteins activate the expression of genes from promoters recognised by core RNA polymerase associated with the alternative sigma-54 factor. These have a ...
